Of 'the above mentioned type that undue heat emanation toward the outside from the supporting frame will be avoided.

is a de viewiof the supportingframe accordtion alongi-ihe line rnqn of Fig. 2 M 'Geiterql arrangement 'l lie primary'feature; ofthe present invention consists in thiitheheated-up cooling air of the superimposed air ice 2 cooled V-engines is discharged through the supporting frame. More specifically, the heated-up cooling air is passed into hollow bodies forming the supports for the engines and is passed through said hollow bodies into further hollow bodies with one or more discharge openings of the supporting frame.

With an arrangement according to the invention, a single air discharge conduit will sufiice which is preferably connected to the top of the engine supports. That portion of this conduit which branches off to the individual engines is arranged within the supporting frame so that a minimum of piping is required while on the otherhand the installation is streamlined and can easily beinspected and observed. Due to the fact that the heated up cooling air is passed from the engines downwardly into the supports, the servicing personnel approaching the'engines from the side are not impeded in their work. Furthermore, a plurality of installations of the type according to the invention can be arranged so closely to each other that there will remain just space enough for an operator or servicing person to pass therebetween.

In conformity with a further development of the invention, also the exhaust gases may be discharged to gether with the heated-up air. An interference of the discharged airstream of one engine by the discharged air stream of theother engine can be avoided by separately guiding the heated-up air streams of each engine along a separate path up to the point Where they leave the supporting frame. If desired the heated-up air streams may be mixed with exhaust gases. Engines or engine parts arranged within the interior of the supporting frame portion carrying the engine supports or engine parts passing through the supporting frame may be protected against hot air by convenient linings or the like. Thus, to prevent too strong a heat emanation from supporting frame surfaces, such surfaces may be provided with a protective layer impeding the heat emanation or heat absorption. If the output shafts of the engines have to pass through the supporting frame, it is suggested according to the present invention that the passages for said output shafts be designed as tunnels and that if necessary blower wheels or the like be mounted on said shafts to produce a cooling air stream around said shafts. If it is not intended to discharge the hot air into the atmosphere but to employ the same for heating purposes, the supportingframe portions carrying the engines may be provided with corresponding connections for connection with conduits leading to the place of consumption of said hot air.

' The supporting frame according to the invention may be I adapted to the respective conditions of operation. Thus,

the lowermost engine support or engine supports may be provided with skid-like structures so that the supporting frame could be dragged over the ground if this should be necessary thereby facilitating the placing of the supporting "frame.

Furthermore, the lower chambers of the lowermost engine .supports'which are not required for conducting air may be designed as container for operating elements, tools and the like.' The supporting frame carrying'the engine supports may be built up as a single box or may form a pluralityof boxes or pipes open at the top.

. Structural arrangement .Referring now to the drawings in detail, the supporting frame shown therein comprises' a box-shaped part 1 which isbpen at theto'p and extends substantially in vertical directionalong one end face of the internal combustion engines 2, 3 (shown in dot-dash lines in Fig. 2 and in solid linesin'jFigQ 3) when the engines are supported bythe sap orts 4,:15 and 7 rspectively. Thesupports 4, 5 and'li, 7 are connected to the box-shapedpart 1 in any convenient manner as for instance by welding or they may be integral therewith. The lower supports 6 and 7 are designed in a skid-like manner so that the entire supporting frame can be dragged over the ground whenever desired and expedient. Furthermore, the lower supports 6, 7 are interconnected by means of a transport rod 8.

As will be evident from the drawing, the supports 4, 5, 6 and 7 are designed as hollow bodies the interior of which communicates with the interior of the frame part 1. All supports 4, 5, 6 and 7 are provided with openings S 19, 11 and 12 respectively at the top. As has been indicated in the drawing by arrows, the cooling air heated up by the engines and leaving the latter along the sides thereof (see Fig. 3) pass through connections 29, 36, 31 and 32 respectively into the supports 4, 5, 6 and 7 and from there flow into the interior of the box-shaped frame part 1. Although not necessarily, the frame part 1 is preferably subdivided by a wall 28 so as to be partitioned into two passages 33 and 34. In such an instance the heated-up cooling air of the motor 2 is conveyed along the wall or guiding metal sheet 13 (see Fig. 2) into the passage 33. The guiding metal sheet 13 is inserted in the support 4 as is clearly shown in Fig. 2. A similar guiding wall or guiding metal sheet (not shown) will be provided in the support 5.

Similarly, the cooling air heated up by the motor 3 passes along a guiding wall or metal sheet 14 inserted into the support 6 and is conveyed along said wall 14 below the partition 28 into the passage 34. The bottom of the passage 33 is, of course, closed with regard to the hollow body 6. it is, of course, understood that the support 7 is provid d with a building wall (not shown) similar to the guiding wall 14, and the bottom of the passage 33 is also closed with regard to the hollow body 7. Thus, it will be clear that the stream of heated-up cooling air from the lower engine 3 will not mix with and will not be interfered by the heated-up cooling air from engine 2 while the heated-up cooling air from both engines passes through the frame part 1. The hot air flowing up the passages 33 and 34 will then be discharged into a manifold (not shown) which is common to both passages 33 and 34 and may be connected to the top of the frame part 1.

Where the output shafts 16 and 17 of the internal combustion engines extend through the frame part 1, the latter is provided with protective walls forming tunnels or passages 18 and 19. Fan or blower blades 22 are connected to the output shafts 16 and 17 and are located within the passages 18 and 19 so as to produce a stream of cooling air around the shaft during operation of the engine to thereby protect the output shafts against any undue accumulation of heat. Preferably, each of the two tunnels or passages 18, 19 are provided with a heat protective layer 36, 35 in order to prevent heating up of the passage walls as far as possible.

According to Fig. 2, the output shafts 16 and 17 lead into a common transmission 20 to which they are drivingly connected and through which they drive a common output shaft 21.

In order to prevent the frame part 1 from being heated up to an undesired extent, or in other words to prevent too great a heat emanation from the frame part 1, the walls of the latter may be lined on the inside with poor heat conducting material such as asbestos or the outside of the frame part 1 may be covered with poor heat condoctors such as asbestos.

Figs. 2 and 3 also show in dot-dash lines the exhaust manifolds 26 and 27 respectively pertaining to the engines 2 and 3. While it is not necessary, it is advantageous to cause the exhaust manifold 26 to discharge its exhaust gases into the passage 33, while similarly the exhaust manifold 27 discharges its exhaust gases into the passage 34.

If it should be desired not to discharge the heated-up cooling air with or without the exhaust gases into the atmosphere but to make use of the heat energy thereof,

the passages 33 and 34 may be provided with connections 24 (the connection for the passage 34 only being shown) through which the heated-up gases will be withdrawn and conveyed to the point of consumption.

The hollow space confined by the lower side of the sheet metal insert 14 and the adjacent portion of the hollow supports 6 and 7 may be used as storage place for tools, oil cans and similar servicing parts. To this end, the hollow supports 6 and 7 are provided with a door (one only being shown in connection with the hollow support 6).

It is, of course, to be understood that the present invention is, by no means, limited to the particular construction shown in the drawings but also comprises any modifications within the scope of the appended claims.
